The DNA of Calabi–Yau Hypersurfaces

open access: yesFortschritte der Physik, EarlyView.
Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

A Novel Crawling Robot Based on the Hexagonal Mesh Structure and Enhanced PID Control Strategy

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The locomotion of crawling robots is similar to that of caterpillars, relying on foot adhesion and body contraction to ensure flexible movement without compromising stability. However, most existing pneumatic soft crawling robots are incapable of simultaneously achieving forward, backward, turning, and climbing capabilities.

Establishing a Model for Serious Science Game Design for Elementary Learners: A Longitudinal, Mixed Methods Study of Serious Game Design Mechanics That Facilitate Science Learning

open access: yesScience Education, EarlyView.
ABSTRACT Immersive learning environments, such as serious educational games (SEGs), offer promising opportunities for enhancing elementary students' science learning outcomes and fostering their interest in science. These environments allow learners to explore scientific phenomena in ways traditional instruction cannot replicate.
